Rooney sensationally told Manchester United he would not extend his stay at Old Trafford beyond the end of his current contract, which expires at the end of next season.

The 24-year-old claims he was motivated over concerns that the Red Devils can no longer compete in the transfer market and is eager to move to a club where he will always be in the hunt for trophies.

Chelsea would certainly fit that bill, given the spending power of owner Roman Abramovich, and Terry knows that a swoop for his England international teammate would benefit Carlo Ancelotti’s squad.

“Wayne is best young player in the world,” Terry said. “I am no different to any other player in saying that. You obviously have to respect Manchester United and Wayne, but who knows what’s going to happen. We’ve got a great squad of players, and he would add to that and strengthen the squad. He is the best player in the world for me.”
